A 67-year-old Dove Creek woman was killed in a crash Saturday night on Colorado Highway 184 between Dolores and Mancos.

Colorado State Patrol Capt. Adrian Driscoll said Lois Marie Oliver of Dove Creek died in the collision after her westbound 2003 Ford F-150 pickup drifted into the eastbound lane and struck a 2017 Dodge pickup driven by Daniel Stephens, 27, of Aztec.

Neither alcohol, drugs nor excessive speed is suspected as contributing factors in the crash. Both Oliver and Stephens were wearing seat belts, Driscoll said.

An investigation continues to determine why Oliver drifted into the eastbound lane, Driscoll said.

The crash occurred just before milepost 15, west of Summit Lake. The call was reported to CSP at about 7:50 p.m. Saturday, Driscoll said.

The vehicles hit left-front to left-front, Driscoll said.

Stephens suffered minor injuries and was not taken to a hospital. Oliver died at the scene, Driscoll said.
